CRYSTALLINE LATEX PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide solvent reuse processes to obtain crystalline polyester (CPE) latex.SOLUTION: A phase inversion emulsification (PIE) method comprises: adding, to an organic mixture comprising a first concentration of a solvent and a base, a crystalline polyester (CPE) resin comprising one or more acid groups; dissolving the CPE in the organic mixture to form a dispersion; neutralizing the one or more acid groups by adding a base to the dispersion to form a neutralized dispersion; and adding an aqueous mixture and optional water to the neutralized dispersion to obtain a phase inverted oil-in-water (O/W) emulsion comprising CPE resin particles.SELECTED DRAWING: None
